Specification of Letters Patent.

Patented July 25, 1916.

Application filed May 25, 1915. Serial No. 30,272.

To all whom it may concern:

Be it known that 1, CHARLES H. BROWN, a citizen of the United States,and a resident of Oklahoma city, in the county of Oklahoma and State ofOklahoma, have invented a new and useful Im )rovement in Desks, of whichthe following is a specification.

My invention is an improvement in desks, and the invention has for itsobject to pr0- vide a device of the character specified, more especiallyadapted for office use, wherein a central support is provided, having aseries of horizontal partitions, and mounted on wheels'or rollers topermit the support to be moved from place to place and in any direction,and wherein the support is provided with series of shelves at sundry ofthe partitions extending laterally outward at angles of 90 with respectto each other to permit either shelf to be used independently of all ofthe others and to permit a number of persons to use the desksimultaneously, and wherein sundry of the shelves are provided withextensions.

In thedrawings:-Figure 1 is a perspective view of the improved desk,Fig. 2 is an enlarged section on the line 22 of Fig. 1, looking in thedirection of the arrows adjacent to the line, Fig. 3 is a perspectiveview of one of the extensions, Fig. 4 is a vertical section, Fig. 5 is aperspective View of a portion of one of the legs of the support, Fig. 6is a vertical section through one of the supporting wheels or rollers,and Fig. 7 is a section on the line 7T of Fig. 6, looking in thedirection of the arrows adjacent to the line.

The present embodiment of the invention comprises a skeleton support,consisting of four legs, posts or pipes, each of which is composed oftwo integral portions 1 and 1", the portions 1 being offset inwardlywith respect to the portions 1. At the upper end of the portion 1 eachpipe is provided with an angular extension 2, and the pipes are arrangedwith the extensions 2, extending inwardly, and they are connected by adisk 3 of suitable material.

A star-shaped bracket 4 is pivoted to the disk, the said disk having acentral opening 5 for receiving pin 6 on the bracket, and a table 7 issecured to the arms of the bracket. The arms of the bracket diverge atangles of 90 with respect to each other,

and they are secured to the under face of the plate or table 7 in anyusual or desired manner.

The pipes 1l are connected at the pertions '1' thereof by a frame 8-ofmetal and of suitable dimensions, the frame being square in the presentinstance, and being arranged at the inner sides of the pipes as shown.The frame is connected to each pipe or leg by means of a rivet 9 or thelike, and the frame holds the legs in proper relation with respect toeach other.

lVheels or rollers are connected with the lower ends of the legs, eachwheel or roller consisting of two disks 10, connected by a headed pin orrivet 11. This pin or rivet passes through central openings in the disks10, the said openings being coaxial, and the pin or rivet is headedatthe outer face of each disk. The portion of the pin that passes throughthe central opening of the disk is reduced to limit the inward movementof the wheelsor disks.

A standard 12 is secured to each pin or rivet at its center, and eachstandard is provided at its upper end with a post 13, and with anannular rib 14 between the post and the body of the standard. This post13 is adapted to engage the lower end of the adjacent pipe and to fittherein, and it will be noted that each pipe is provided at its lowerend with a marginal rib 15, resting upon the upper face of the rib 14and of the same external diameter.

A union in the form of a washer 16 is provided for connecting eachstandard to the adjacent pipe, each of the said washers 16 havingdepending pins 17 at its periphery, which engage notches 18 and 19 inthe ribs 14 and 15, respectively. The engagement of,

the pins with the notches prevents angular movement of the bracket andwheels with respect to the post or leg, and the parts are soarrangedthat the axes of the wheels at diagonally opposite posts or legswill b parallel;

Two bars 20 of angle material are secured to the posts near the lowerends of the pore tions 1*" thereof. Each bar 20 is'connected to twoposts, being arranged on the inner sides thereof, and the bars aresecured to the posts in any suitable or desired manner. Each bar has avertical portion which is secured to the post and a horizontal portionposts and at the same level with the bars 20.

These bars are arranged with their horizontal portions inwardly, andplates or tables 23 are'secured to the portions of the bars bymeans ofscrews 24, or thelike. The bars 20 extend beyond the support at eachend, and similar plates or tables 28 are secured to thehorizontalportions of the bars.

Thus fourof the tables 23 are provided, one plate or table extendingoutwardly. from a each of the sides of the plate 21.

Itwill be noticed from an inspection of Fig. A, that the plates 23 areof greater thickness than the plate 21," and since. the

horizontal portions of the bars 2022 are arranged with their uppersurfaces in the same planethe upper surfaces of the plates 23. are abovethe upper face of the plate 21.

Channel bars are secured to the portions 1' of. the posts about half waybetween @the plate or table 7 and the plate or table 21,

the said channel bars being parallel with the bars 20, and secured tothe pipes'at, the inner sides thereof. .The channel bars 25 are arrangedwith their channels inwardly, and other pairs of channel bars 26 arearranged V parallel with the bars 22. Each pair of channel bars, 26 isparallel to the adjacent pair of bars 22, and these bars 26 are arrangedwith, respect to the bars 25 in the same manneras are the bars 22 withrespect to the bars 20 V A plate 21 is'sup-ported on theupper flanges ofthe channel bars 25, the said plate being square and similar to theplate 21, be-

fore mentioned. Other plates or tables 23 similar in all respects'totheplate 23, are arranged on the extended ends of the channelbars 25 and onthe channel bars 26. The plates 23 are secured to the upper. flangesofthe channel bars 25 and 26, by means of screws 2 7'orthe like. j i

A plate or slide 28 is mounted in the channels of each pair of channelbars 26 i and in the channels at each end of the bars 25, the slide barsbeing of alength to extend from the outer ends of the plates 23 to theadjacent pair of pipes ;1 and 1*, when the extensions arein inwardposition.

Each extension is provided with a handle in the form of a loop or bailon its under side, eachlo'op or'bail comprising a body 29 and arms 30,secured to the under face ,of the plate. ,A second handle or support isconnected'to each slide plate at the outerend "thereof, each of the saidhandles or supports comprising abody31 and arms 82, ex- :tendinglaterally from the'ends of the body. Each arm 32 is provided Withalateral lug 38 at the end remote from the body, and extendingat rightangles to the arm, and

these lugs are secured to the under face of the plate in any suitablemanner outside the ends of the handle 2930. The handles 3132-33 are soarranged that the bodies of the bails will be above the table 23 and atthe outer end thereof, while the handle 29-30 is so arranged that thebody thereof will be below the plate 23 and spaced down wardlytherefrom.

The outer ends of the bars 26 and the outer ends of the bars 25 arebraced against the pipes'by inclined braces 34. The said I braces areornamental in form, and each -brace is secured at one end to the outerface of the adjacent bar andat the other end to the adjacent pipe orleg.

The improved. desk requires but little floor surface,and since eachofthe extensionsis spaced apart from all of the other extensions anyextension is easlly accessible,

and may be used independentlyof the others. The several extensions orshelves may be extended by pulling out. the adjacent slide,

about twice the usual length.

The improved desk is not liable to tip over, because of the broad base.The plates 72121 may be used'for storage, while the shelves proper maybe used for work or for storage. For office use, the desks are thismaking each shelf of the upper'series i very convenient for books. Thebook will table the locking rings 16 17 may be lifted upward to'releasethe ribs 14 and 15 from each other. When so released the rollers arecasters. When the locking rings. are

'dropped however, the wheels are locked,

locking the support against movement in any direction. I

It is obvious that with the wheels locked, they cannot roll freely in;any direction. When released however, all may'take'a po- -sition withtheir axes parallel to permit the fre rolling of the support. Iclaim:* m5' 1.
